Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562204, here are decompositions:

67 + 31562137 = 31562204
97 + 31562107 = 31562204
151 + 31562053 = 31562204
181 + 31562023 = 31562204
211 + 31561993 = 31562204
277 + 31561927 = 31562204
397 + 31561807 = 31562204
607 + 31561597 = 31562204

Showing the first eight; more decompositions exist.
